Objective To probe the effect of perioperative therapeutic regime on breast reconstruction after surgery in breast cancer patients.Methods We retrospectively reviewed the clinical data of 145 consecutive breast cancer patients with 162 reconstructions.Results 127 of 145 patients got an excellent or good appearance (87.6％),and 42 cases had complications occurring in 162 operations (25.9％).After a median follow-up of 38.4 months,recurrences were found in 9 patients,3 cases died,and the disease free survival rate was 93.1％.Multivariate analysis showed that radiation therapy,without nipple-sparing and one-stage prosthesis implant were independent risk factors for negative postoperative aesthetic outcome;Delayed reconstruction and implant reconstruction were found to be protective factors for the postoperative complications.Conclusions Although the survival rate appears to be scarcely affected,different treatment modalities in reconstruction strategy bring different clinical results and outcomes.The perioperative decision-making of reconstruction strategy should be based on oncological safety,postoperative complications,aesthetic outcomes and subsequent therapies.

Objective We tried to design a Instructor Rating Scale Identified by Nursing Students,and then evaluate its rehability and validity.Methods The original item pool was formulated by investigating 351 nursing students with convenience samphng method to develop a prehminary scale.Then it was used to investigate 273 nursing students to test its rehability and validity.Results The formal scale consisted of six dimensions,which contained 19 items.The cumative contribution rate of these dimensions was 62.30％.The Cronbach's α coefficient was 0.54,test and re-test reliability was 0.48.Conclusions The Instructor Rating Scale Identified by Nursing Students can be applied to evaluate the instructors by nursing students.

Objective To optimize the synthesis process of istradefylline 1 for industrial production.Methods Istrade-fylline was synthesized from dimethyl carbonate and ethylamine through a series reactions including condensation,cycliza-tion,nitrosation,and reduction to produce 1,3-diethyl-5,6-diaminouracil(6),which was subjected to amidation with (E)-3,4-dimethoxycinnamic acid (8),followed by cyclization and methylation reaction.Compound 8 was prepared from veratr-aldehyde and propanedioic acid by Knoevenagel condensation.The structures of intermediate and target compounds were confirmed by MS and 1 H-NMR.Results and Conclusion The quality control points of each key process were optimized so that the total yield was 26.2% and the purity of the product was 99.76%.This improved synthesis method has some advan-tages,such as mild reaction conditions,simple operation,and applicability to industrial production.

Objective To investigate the correlation between vitamin A,E,D and folic acid levels and concomitant preeclampsia(PE)in patients with gestational diabetes mellitus(GDM).Methods A total of 108 patients with GDM complicated with PE were used as the PE group,and another 108 GDM patients without PE were used as the GDM group.A total of 108 normal pregnant women with normal pregnancy test were used as the normal control group.The general information and vitamin A,E,D and folic acid levels were compared between the three groups.According to the severity of the disease,the PE group was subdivided into the mild-moderate PE group(62 cases)and the severe PE group(46 cases),and vitamin A,E,D and folic acid levels were compared between these two groups.Results Systolic blood pressure(SBP),diastolic blood pressure(DBP),fasting blood glucose(FBG),fasting insulin(FINS)were increased in turn in the normal control group,the GDM group and the PE groups(P＜0.05),and vitamins A,E,D and folic acid levels were decreased in turn(P＜0.05).Triglyceride,total cholesterol and glycated haemoglobin were higher in the PE group than those in the GDM group and the normal control,and high density lipoprotein(HDL)cholesterol was lower than that in the GDM group and the normal control group(P＜0.05).Vitamin A,vitamin E,vitamin D and folic acid levels were lower in the severe PE group than those in the mild to moderate PE group(P＜0.05).Higher levels of vitamin A,vitamin E,vitamin D and folate were protective factors for GDM patients with severe PE.Folic acid showed higher predictive efficacy and specificity in single indicator analysis.Vitamin A showed high predictive specificity.The combined prediction of four indicators for severe PE in GDM patients was more effective than each individual indicator.Conclusion Serum vitamin A,E,D and folate levels are significantly lower in patients with GDM complicated with PE,and the combination of all four may improve the predictive value of severe PE complicated with GDM.

OBJECTIVESTo evaluate the safety and effectiveness of open preperitoneal herniorraphy comparing with traditional Lichtenstein tension-free herniorraphy on the surgical treatment of inguinal hernia.

METHODSThe clinical data of 249 patients with inguinal hernia admitted from October 2008 to December 2013 were reviewed retrospectively.Eighty-three patients received preperitoneal herniorraphy (preperitoneal group), there were 76 male and 7 female patients with a mean age of (70 ± 10) years.One hundred and seventy-three patients underwent Lichtenstein procedure (Lichtenstein group), there were 162 male and 11 femal patients with a mean age of (60 ± 16) years. The peri-operative performance, recurrence rate and postoperative morbidities of the patients underwent preperitoneal herniorraphy and traditional Lichtenstein herniorraphy were analyzed.

RESULTSThe operation time of the preperitoneal group (60 ± 11) minutes was significantly shorter than the Lichtenstein group (63 ± 8) minutes (t = -2.16, P = 0.032). The preperitoneal group showed significantly earlier out-of-bed activity ((6.2 ± 1.8) hours) than the Lichtenstein group ((15.0 ± 2.8) hours) (t = -13.2, P = 0.000). The visual analogue scale score on 24 hours postoperative was also lower in the preperitoneal group (4.0 ± 0.9) than in the Lichtenstein group (4.6 ± 1.4) (t = -4.11, P = 0.000). The two groups had no significant difference on the cost. There was one incision infection in preperitoneal group (1.20%).Four fat liquefaction (2.31%) and one patch rejection (0.58%) were found in Lichtenstein group. The incidence of complication of the two groups had no significant difference (P > 0.05). All the patients were followed up for 6 to 36 months, and there was no recurrence among all these patients.

CONCLUSIONSThere is no significant difference on the safety and effectiveness between preperitoneal herniorraphy and traditional Lichtenstein procedure on inguinal hernia.Open preperitoneal herniorraphy and can be applied for surgical treatment of recurrent or femoral hernia.
